6 Claims. ((11. 189-46) This invention relates to improved pilasterstructures and hinge bracket assemblies in which the door supportinghinge brackets are rigidly secured to the jamb edge of the pilaster incantilever suspension and without attachment to the side faces of thepilaster. This application is a continuation-in-part of my copendingapplication Serial No. 696,864 filed November 15, 1957, now US. Patent2,876,874 issued March 10, 1959, and a division of my copendingapplication Serial No. 795,683 filed February 26, 1959.

Hinge brackets made in accordance with this invention are particularlydesigned for cantilever attachment to frame structures, posts andpilasters whose jamb edge is of relatively narrow width, and areparticularly designed for attachment to the jam-b edge of hollow metalpilasters which measure only one to two inches or less in thickness, andwhich form the supporting uprights for interior cubicles, such as toiletand hospital cubicles, and the like.

A typical hollow metal pilaster with which the hinge brackets of thisinvention may be associated, may be formed by a pair of spaced metalfacing sheets bonded to a reinforcing core of sound deadeninginsulation, and which present paired inturned flanges along the exposedvertical and horizontal edges thereof. The paired inturned flangespresent a pair of outturned lip portions formed integral therewith andjoined together by exteriorly applied spot welds to provide a rigidpilaster construction. Edging strips of semi-tubular cross section, andpresenting a contoured facing portion and paired inturned lip portions,are telescoped over the outturned lip portions of the pilaster body tointerlock therewith. The applied edging strips thus supply a finishedappearance to the exposed vertical and horizontal edges of the pilaster.

The improved hinge brackets of this invention may be die cast orotherwise formed as integral units to present a laterally extending doorsupporting arm section on which the door is swingably mounted. Thesehinge brackets are designed to be mounted on the janr'b edge of arelatively thin pilaster by means which engage or interlock with a jambportion of the pilaster or with associated parts applied to or builtinto the pilaster during its manufacture. Where the hinge bracketincludes an exterior body section from which the arm supporting sectionlaterally extends, the body section thereof is equipped with means torigidly secure the same to a formed jamb portion of the pilaster andbetween the terminal ends of the contoured jamb facing portions thereof,and with the exposed outer face of the bracket body section in contoursymmetry with the outer faces of the contoured jamb facing portions ofthe pilaster.

In one form of this invention, a steel locking channel may be secured tothe fiat j amb portion of the pilaster body between the terminal ends ofthe contoured jamb facing portions thereof, and which is designed tointerlock with a corresponding female formation on the rear face of thebracket body section.

In another form of this invention, the rear face of the bracket bodysection may be provided with a V-shaped groove designed to telescopeover adjacent outturned lip portions of the pilaster body with thebracket body section rigidly locked thereto by one or more deformingwedges "ice driven between the outturned 'lip portions to thereby deformthose sections of the outturned lip portions which are encased withinthe bracket body section.

All forms of this invention feature hinge brackets which are inarchitectural symmetry and harmony with the adjacent contoured jambfacing portions of the pilaster body, and with the exposed sections ofthe hinge bracket confined to the jamb edge of the mounting pilaster.The laterally extending door supporting arm sections of these hingebrackets present a pin-tle hole formed to receive a hinge pintleassociated with a bracket counterpart applied to either the upperportion or lower portion of the mounted door. By the use of these hingebrackets, the pilaster is not defaced by bracket side flanges whichtelescope over the sides of the pilaster and secured thereto by bolts orscrews as heretofore used, but on the contrary, the exposed surfaces ofthese hinge brackets are contoured in blended symmetry with the jambedge of the pilaster to provide a door supporting structure ofarchitectural harmony and beauty.

These improved pilaster structures and binge bracket assemblies are soconstructed as to insure precise alignment of the upper and lower hingebrackets and accurate hanging of the door without field adjustment.These hinge brackets may be economically die cast or otherwise assembledas an integral unit at substantially less cost than door supportinghinge brackets heretofore made, can be attached to a floor supported orceiling hung pilaster during manufacture thereof, and as mountedthereon, present an assembly which is substantially free of projectionsand crevices in which dirt would collect.

Other objects and advantages of this invention will become apparent asthe disclosure proceeds.

All of the door supporting hinge brackets constructed in accordance withthis invention are particularly designed for attachment to the jamb edgeof hollow metal posts or pilasters which may be either floor supportedas shown in FIG. 1 or ceiling supported as shown in H6. 2. These doorsupporting pilasters are particularly adapted for assembly into interiorcubicles, such as hospital and toilet cubicles.

The floor supported pilaster 1 as shown in FIG. 1 and the ceiling hungpilaster 1 as shown in FIG. 2, and with which the door supporting hingebrackets of this invention are particularly adapted for attachment,comprise a pair of pilaster facing sheets 2"'2 formed from sheet metalor other strong sheet material, which together present inturned flanges3-3 along the exposed vertical and horizontal edges thereof. Each pairof inturned flanges 33 incorporate outturned lip portions 4 which aresecured together by suitable spot welds 4 exteriorly applied to thepaired outturned lip portions at the crotch area between them as shownin FTGS. 4 and 9. Prior to spot welding together the paired inturned lipportions 4 to provide a rigid pilaster construction, a reinforcing andinsulating core 5 is first adhesively bonded to the inside face of oneof the pilaster facing sheets 2, and the exposed face of the reinforcingcore is then coated with adhesive and the other facing sheet 2 thenapplied thereto. Pressure is then applied to the sandwich as thus formedto insure a firm adhesive bond between the reinforcing core 5 and theinside faces of the pilaster facing sheets 2-2. The reinforcing core 5is desirably composed of a relatively hard, pilaster sheet bracing andsound deadening insulation packing, such as slabs of fibreglass,honeycomb fibreboard or other core material which is relatively light inweight, capable of deadening sound, and capable of bracing andsupporting the pilaster facing sheets 2-2 to which the reinforcing core5 is adhesi-vely bonded.

The exposed vertical and horizontal edges of the pilasters 1-1 aretrimmed by means of edging strips 6 of semi-circular cross-section andsimilar in size and contour. Each edging strip 6 presents a face portion6 of generally curvilinear form which terminates in inturned lipportions 7. The edging strips 6 are designed to be telescopedlongitudinally over the outturned lip portions 4 of the pilaster facingsheets 2-2, so that the inturned lip portions 7 of the edging strip willinterlock with and be firmly secured to the outturned lip portions 4 ofthe pilaster facing sheets 2--2 as shown in FIGS. 1, 2, 3 and 8.

During manufacture of the sheet metal panel facing sheets 2-2 of thepilasters 1 and 1, suitable cut-outs, deformations or additions may bemade in or to those areas of the inturned flanges 3 and outturned lipportions 4 to which the door supporting hinge brackets of this inventionare to be applied, to thereby provide suitable seating faces andanchoring means for rigidly securing the selected hinge bracket to thejamb edge thereof, as more fully hereafter explained. All of the hingebrackets of this invention are particularly designed to be applied tothe prepared areas of the inturned flanges 3 0f the panel facing sheets22, either before the lip portions 4 of the panel facing sheets havebeen spot welded together, or after the reinforcing core 5 has beenpositioned between the panel facing sheets and the outturned lipportions 4 thereof welded together as heretofore explained.

The floor supported end of the pilaster 1 as shown in FIG. 1, and theceiling supported end of the pilaster shown in FIG. 2, are suitablysecured to the floor or ceiling Wall by suitable brackets and lag boltsas shown in FIGS. 1 and 2. The floor or ceiling supported end of thepilaster and associated wall securing means, are concealed within atrimming shoe 8 as shown in FIGS. 1 and 2 which snugly telescopes overthe pilaster and snugly seats against the horizontal building wall towhich the end of the supported pilaster is attached.

The door supporting hinge bracket G shown in FIGS. 3, 5, 6 and 7, isdesigned to be mounted on the jamb face of the hollow metal pilaster 1or 1 and to seat against the adjacent flange portions 17 of the pilasterbody as shown in FIG. 4, and held thereto by a snap fastener in the formof a snap lock channel 54. The hinge bracket G may be die cast as anintegral unit to provide a door supporting arm section 20 extending froma body section 50 which presents a curvilinear outer face 50 in contourconformity to the outer faces of the curvilinear face portions 6 of theupper and lower edging strips 6 applied to the pilaster body. The hingebracket G may be used as an upper hinge bracket, or a lower doorsupporting hinge bracket, by providing a pintle hole 20' therein toreceive an upper door hinging pintle, or a pintle hole 20" therein whichsupports a lower pintle on which the door is swingably supported.

The bracket body section 50 may present square cut ends 50 against whichthe terminal ends of the upper and lower edge moulding strips 6 aredesigned to abut, to thereby provide substantially flush and single linejoints therebetween. The upper and lower ends of the body section 50 mayalso be provided with a tongue or a pair of spaced vertically extendingstuds 51 at one or both ends thereof which are designed to telescopeinto the adjacent end of the semi-tubular edge moulding strip 6.

The body section 50 also presents a pair of spaced rear facing portions52 which define a vertically extending locking groove 53 therebetween,as shown in FIGS. 3 and 7. The locking groove 53 presents side ledgeportions 53 designed to interlock with a snap-lock channel 54 which isfirst applied to the jamb face of the pilaster body as shown in FIG. 4.The spaced rear facing portions 52 of the bracket body section 50 aredesigned to flatly seat against the outside faces of the inturned flangeportions 17 of the pilaster body when the bracket body section 59 hasbeen pushed into locking relation with the snap-lock channel 54.

The snap-lock channel 54 presents a web portion 54' which seats againstthe outside faces of the inturned flange portions 17 of the pilasterbody. The snap-lock channel 54 also presents side flanges 54"terminating in resilient curvilinear n'm portions 54 designed to snapinto interlocking engagement with the side ledge portions 53' of thelocking groove 53 formed in the rear face of the bracket body section59. The web portion 54' of the snap-lock channel 54 is rigidly securedto an internal bracing plate 18 which seats against the inside faces ofthe inturned flange portions 17 of the pilaster body as shown in FIG. 4,and is secured thereto by suitable metal screws 18".

In manufacturing the pilasters 1 and 1' to support one or more of thehinge brackets G, the inturned flanges 3 of the pilaster facing sheets22 are formed to provide the usual outturned lip portions 4 above andbelow the area where the hinge bracket G is to 'be applied, leavinglipless inturned flange portions 17 therebetween which provide a flatseat for the spaced seating portions 52 of the bracket body section 54).A sturdy bracing plate 18 is positioned adjacent the inside face of theinturned flange portion 17 of one of the pilaster facing sheets andsecured as by spot welds 17 thereto. After the reinforcing core 5 hasbeen adhesively bonded to this pilaster facing sheet 2, the companionpilaster facing sheet 2 is applied thereover and adhesively bonded tothe adjacent face of the reinforcing core 5. The inturned lip portions4- are then secured together by the application of a series of spotwelds 4 in the crotch therebetween as shown in FIG. 4. The terminal ends4 of the existing lip portions 4 are sufficiently spaced to permit theapplication of the body section 45 of the hinge bracket G to theinturned flange portions 17 therebetween. The inturned flange portions17 of the second and companion pilaster facing sheet 2 may also be spotwelded or screwed to the underlying bracing plate 18. The snap-lockchannel 54 is then placed in seating position against the outside facesof the flange portions 17, and rigidly held in position by two or moremetal screws 18 extending through the web portion 54 thereof and screwedinto tapped holes provided in the internal reinforcing plate 18.

The bracket body section 59 is then applied by telescoping the lockinggroove 53 in the rear face thereof over the side flange portions 54" ofthe snap-lock channel 54 until the resilient curvilinear rim portions54" thereof snap into interlocking engagement with the side ledgeportions 53' of the locking groove. The spaced rear facing portions 52of the body section will then snugly seat against the outside faces ofthe inturned flange portions 17 of the pilaster body.

The upper and lower moulding strips 6 are then telescoped over theoutwardly flared lip portions 4 of the pilaster body as indicated inFIG. 3, and the terminal ends thereof placed in abutting relation to thesquare cut ends 50 of the bracket body section 50, and with the lockingstuds 51 snugly telescoped into the adjacent terminal end portion of thesemi-tubular edging strip 50.

The hinge bracket G is thus rigidly and securely mounted on the jambface of the pilaster by the snap-lock channel '54 whose resilientcurvilinear rim portions 54" are in looking engagement with the sideledge portions 53" of the locking groove 53- extending vertically alongthe rear face of the bracket body section 541*. This bracket is furtherbraced by the spaced rear facing portions 52 extending along the lockinggroove 53, and which snugly seat against the outside faces of theinturned flange portions 17 of the pilaster body. The hinge bracket Gmay be further rigidly fixed to the jamb face of the pilaster body bythe provision of tongues'or studs 51. which project from the upper andlower ends of the bracket body section 50 and into the end of theadjacent semi-tubular edging strip 6, and with the three sides of eachstud 51 in bracing relation to the inside faces of the curvilinearportion 6' and the inturned lip portion 7 of the edging strip 6, and theface or edge of the adjacent lip portion 4 of the pilaster.

As thus assembled, the curvilinear outer face 50' of the bracket bodysection St} is in streamlined symmetry with the outer curvilinear facesof the applied edging strips 6, with no bracket securing meansexteriorly visible when the hinge bracket G is fully assembled on itssupporting pilaster.

The door supporting hinge bracket H shown in FIGS. 8, 10, 11 and 12comprises a body section 55 having a door supporting arm section 20extending therefrom. The body section has a V-shaped locking groove 58in the rear face thereof which is designed to telescope over theoutturned lip portions 4 of the pilaster body as shown in FIG. 9, and toseat against the inturned flanges of the hollow metal pilaster 1 or 1,and held thereto by a locking wedge 19. The hinge bracket H may be diecast as an integral unit, with its body section 55 shaped to present acurvilinear outer face 55 in contour conformity to the outer faces ofthe curvilinear face portions 6- of the upper and lower edging strips 6locked to the outwardly flared lip portions 4 of the pilaster body. Thehinge bracket H may be used as an upper hinge bracket, or a lower doorsupporting hinge bracket, by providing a pin-tle hole 20 therein toreceive an upper door hinging pintle, or a pintle hole 2t) therein whichsupports a lower pintle on which the door is swingably supported.

The bracket body section 55 presents square cut ends 56 against whichthe terminal ends of the upper and lower edge moulding strips 6 aredesigned to abut, and to thereby provide substantially flush and singleline joints therebetween. The body section 55 also presents a pair ofspaced rear facing portions '57 which define a vertically extendingV-shaped locking groove 58 therebetween as shown in FIGS. 8 and 12. Thelocking groove 58 presents inclined side face portions with whichadjacent lip parts 4a4a of the pilaster body are designed tofrictionally interlock. The locking groove 58 is defined between spacedrear facing portions 57 designed to flatly seat against the outsidefaces of the adjacent inturned flanges 3 of the pilaster body.

The lip parts 4a4a of the outturned lip portions 44 which extend intothe V-shaped locking groove 58 of the bracket body section 55, arelaterally expanded into frictional locking engagement with the sidefaces of the V-shaped locking groove 58 by one or more locking wedges 19which are driven into the locking groove 58 through the open endsthereof. Each locking wedge 19 is shaped to deform and swedge the lipparts 4a4a into frictional locking engagement with the inclined insidefaces of the adjacent rear facing portions 57 of the bracket bodysection. The deformation of the outwardly flared lip parts 4a4a may befacilitated by providing transverse cuts 4b-4b to separate the upper andlower ends of the outwardly flared lip parts 4a4a from the adjacentoutwardly flared lip portions 44 of the pilaster body.

Each of the locking wedges 19 may be made from a steel strip ofsubstantial thickness, and shaped to provide inclined side edges 19' asshown in FIG. 13. The insert end 19 of the locking wedge 19* is slightlytapered to facilitate insertion thereof into the V-shaped locking groove'58 of the bracket body section 55 as telescoped over the outwardlyflared lip parts 4a4zz of the pilaster body. The locking wedge 19 isprovided with side bulge portions 19" directly above the tapered end 19"thereof, which serve as camming anvils to further outflare the lip parts4a4a into frictional locking engagement with the adjacent inclined sidefaces of the spaced rear facing portions 57 which define the V-shapedgroove 58 of the bracket body section. The deformation of the outfl-aredlip parts ta-4a results from the spreading action exerted by the bulgeportions 19" of the looking wedges 19' as. driven into the opposite endsof the V-shaped groove 58 of the applied bracket body section. Thedeformation of the lip par-ts 4a4a also serve to offset the ends of thelip parts 4a-4a with respect to the adjacent cut ends of the lipportions 4-4 of the pilaster body, and thereby prevent the possibilityof vertical movement of the bracket body section 55 as locked to the lipparts 4a-4a by the locking wedges 19.

In manufacturing the pilaster .1 or 1 to support one or more of thehinge brackets H, a reinforcing core is adhesively bonded to the insideface of one of the panel facing sheets 2, and the companion panel facingsheet 2 is then adhesively bonded to the other side of the reinforcingcore. Spot welds 4' are applied at spaced intervals to the outwardlyflared lip portions 4 in the crotch area therebetween to provide arigidly assembled pilaster body. Additional seam welds 40 may be appliedto the crotch area of the lip parts 4a which is to be encased by thebracket body section 55. Transverse cuts 4b4b can then be made toseparate the ends of the lip parts 4a-4a from the adjacent ends of thelip portions 4-4, the cuts 4b4b which define the ends of the lip parts4a4a being spaced in conformity with the length of the bracket bodysection 55.

The hinge bracket H is then applied by telescoping the V-shaped lockinggroove 58 of its body section over the upper or lower'terminal ends ofthe lip portions 44, which terminate at both the upper end and the lowerend of the jamb portion of the pilaster body, and then sliding thebracket body section 55 into telescoped position over the lip parts 4a4awhere the hinge bracket is to be fixed in position. A locking wedge 19,shaped as shown in FIG. 13, is then inserted into one end of theV-shaped groove 58, and preferably a similar locking wedge 19 is alsoinserted through the other end of the V-shaped locking groove 58. Bothlocking Wedges 19 may be simultaneously driven into the groove 58 of thebracket body section 55 so that the located position of the bracket bodysection is not disturbed.

As the upper and lower locking wedges 19 are driven into the V-shapedgroove 58 of the body section, the encased lip parts 4a-4a are swedgedoutwardly into frictional locking engagement with the inner inclinedside faces of the spaced rear facing portions 57 which define theV-shaped groove 58, thereby rigidly locking the bracket body section tothe pilaster body, and with the spaced rear face portions 57 thereof infirm seating position against the outside faces of the adjacent inturnedflanges 3 of the pilaster body. The upper and lower edge moulding strips6 are then telescoped over the outwardly fiared lip portions 4 of thepilaster body as indicated in FIG. 8, and the terminal ends thereofplaced in abutting relation to the square cut ends 56 of the bracketbody section 55. Since the inturned lip portion 7 of the edge mouldingstrips 6 interlock with the outturned lip portions 4--4 of the pilasterbody with substantial friction, the terminal ends of the moulding strips6 which abut the square cut ends 56 of the bracket body section alsoprovide support for the bracket body section 55 which further preventsany longitudinal movement of the hinge bracket H along the jamb portionof the pilaster.

As thus assembled, the hinge bracket H is rigidly and immovably lockedto the jamb portion of the pilaster 1 or 1, with the curvilinear outerface 55' of the bracket body section 55 in streamline symmetry with theouter curvilinear faces of the applied edging strips, providing flushsingle line joints therebetween as shown in FIG. 8, and with no bracketsecuring means exteriorly visible.

The hinge brackets made in accordance with this invention, may beprovided with studs, wings or tongues which project from the ends of thebody section and designed to interlock with the adjacent terminal endsof jamb edge mouldings, such as the hinge bracket G shown in FIG. 3. Thehinge bracket G shown in FIG. 3, and hinge bracket H shown in FIG. 8,normally require a pilaster equipped with slidable edge moulding stripswhich may be slidably telescoped over the end studs 51,

or end wings or end tongues, or the ends of the wedges 19 projectingfrom the ends of the bracket body section.

It will also be appreciated that a bracket of the type similar to type Gshown in FIG. 3, may also be applied to a pilaster having a fixed jambface moulding portions 6, by eliminating the end studs 51 from the bodysection 50 of the hinge bracket G to thereby provide square cut ends,and by securing the snap lock channel 54 as by metal screws 18" to thebracing plate 18 as shown in FIG. 4, and with the spaced rear faceportions 52 of the bracket body section 56 seating against thecomplementary inturned flange portions 3-3 of this pilaster.

It will be appreciated by those skilled in the art, that certain partsassociated with one or more of the hinge brackets of this invention maybe interchangeably applied and substituted for corresponding parts ofother hinge brackets as above disclosed. For example, the insert studs51 associated with the bracket G as shown in FIG. 3, may also be appliedto the upper and lower ends of the body section 55 of the hinge bracketH shown in FIG. 8.

It will be particularly noted that all of the hinge brackets of thisinvention are directly supported from the jamb portion of a pilasterbody, and do not overlap the side panel facing sheets of the pilasterbody, and are particularly designed to be rigidly secured to the jambedge portion of relatively thin pilaster bodies which may measure onlyone inch in thickness. The door supporting hinge and pilaster structuresof this invention present an assembly wherein the exterior faces of thehinge brackets are in contoured symmetry with the ex posed faces of thepilaster edge moulding strips 6, and as assembled, present fine linebutt joints therebetween which are scarcely discernible, and wherein thehinge bracket is securely locked and held in fixed position.

Pilaster structures and hinge bracket assemblies made in accordance withthis invention feature the elimination of bracket side flanges and otherprojections heretofore used to secure the hinge bracket to the pilaster,and which provide areas for the collection of dirt and foreign matterwhich cannot be readily removed. The hinge brackets of this inventioncan be cast or formed in one piece, at substantially less cost than doorsupporting hinge brackets heretofore made and used, and can be mountedon the jamb edge of the pilaster at the factory in precise doorsupporting alignment, and with less labor and less cost than thepilaster and hinge bracket assemblies heretofore made and used. Thenecessary modifications to the jamb edge of the pilaster bodies can beaccomplished in accord ance with this invention at minimum cost whencutting and fabricating the panel facing sheets, or during assembly ofthe pilaster body.

While certain novel features of this invention have been disclosedherein and are pointed out in the claims, it will be understood thatvarious omissions, substitutions, and changes may be made by thoseskilled in the art without departing from the spirit of this invention.
